I think "snowless snowy grass", and "negative durability item" would be great categories. I'm surprised negative durability doesn't already exist. There is actually a better way to get player heads, which is 20w14inf, go to the ~N dimension, and there is always a player head at (190, -60) supposedly. Which is a much more reasonable method, and I think fits nicely. As for milk from squids, yeah it's not discontinued, but it is definitely "weird", if there were to be a misc section, I think honestly it could go there, but currently there isn't, and I don't see a reason for there to be, unless there are similar categories which are debated. In my mind snowy grass block, negative durability item, and player head, should almost certainly be added. I'm worried about the enchantments because of the difficulty and length? But it might be fine. I am debating though, if player head were added, would it go in item or block? It fits both
